Description

Technical Field

[0001] This invention belongs to the field of computer technology, and specifically relates to an assembly system and method for a desktop computer. Background Technology

[0002] A desktop computer is a standalone computer, completely independent of other components. Compared to laptops and netbooks, it is larger in size, and its main unit, monitor, and other devices are generally independent. It usually needs to be placed on a computer desk or a dedicated workbench. A desktop computer typically includes a main unit and a monitor.

[0003] The hardware system of a host computer includes: chassis, power supply, hard drive, memory, motherboard, CPU, optical drive, sound card, network card and graphics card, etc. Some components can be integrated together or some components can be omitted. For example, the CPU and graphics card can be integrated together, the sound card, network card and motherboard can be integrated together, and the optical drive can be omitted.

[0004] The assembly of the host is usually done manually and is typically done through multiple workstations. After the host is assembled, it needs to undergo a number of tests, such as whether it can be powered on, whether the display is normal, whether the sound card is normal, whether the fan is normal, whether the appearance is normal, and whether the accessories are complete.

[0005] For example, patent application number CN202020289065.3 discloses a computer host assembly device, including a fixture return line, a feeding line, and an assembly module. The assembly module is located next to the fixture return line and includes a locking platform, a first robotic arm, and a second robotic arm. The fixture return line drives the fixture to rotate, and the fixture carries the mounting frame of the host component. The first robotic arm is used to grab the mounting frame from the fixture and place it on the locking platform. The locking platform is used to position the mounting frame. The second robotic arm is used to grab the host component from the feeding line and lock the host component to the mounting frame. This assembly device only performs assembly and does not perform testing.

[0006] For example, patent application number CN201820938970.X discloses a double-layer high-speed chain conveyor line, including an upper conveyor belt, with lifting and return stations connected to both ends of the upper conveyor belt, and a lower conveyor belt positioned directly below the upper conveyor belt. An upper conveyor belt motor is mounted on one end of the upper conveyor belt via a mounting base, and a lifting machine and a blocking mechanism are installed above the upper conveyor belt to position the tooling fixture. A tray supporting the tooling fixture is fixed to the lifting end of the lifting machine. A lower conveyor belt motor is mounted on one end of the lower conveyor belt, driving its operation. The lifting and return station has a frame fixed inside, and a housing fixed at the top of the frame. A transfer lifting cylinder is longitudinally installed on the side wall of the frame at the center line. A first rotating shaft is rotatably connected to the inside of the housing, and a second rotating shaft is rotatably connected to the inside of the housing at a position parallel to the first rotating shaft. A return station belt motor is installed at the bottom inside the housing, and a positioning cylinder is fixedly installed at the bottom inside the housing near the first rotating shaft. One end of the first rotating shaft and the second rotating shaft are rotatably connected via a transfer belt. The upper conveyor belt motor, the lower conveyor belt motor, and the return station belt motor are all electrically connected to an external controller. This production line is only suitable for the testing or assembly of general electronic products and has poor applicability to mainframes (which require assembly and testing).

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1 See Figure 1-15Example 1 provides an assembly system for a desktop computer, which includes a high-speed conveyor line, a return conveyor line 1, a lifting return station, a product output line 3, and multiple fixtures 2.

[0026] The system includes four lifting and return stations: a fixture lifting conveyor structure 6, a fixture lowering conveyor structure 7, a main unit lifting conveyor structure 8, and a main unit lowering conveyor structure 9. The double-speed conveyor line comprises an assembly conveyor line 11, a testing conveyor line 12, and an upper conveyor line 13. The double-speed conveyor line is a common double-speed conveyor structure, consisting of two synchronous belts or conveyor chains arranged side-by-side and driven synchronously, each composed of one or more double-speed conveyor structures. The fixture lifting conveyor structure 6, fixture lowering conveyor structure 7, and return conveyor line 1 work together to circulate the empty fixture 2 (on which a soft pad 5 is placed). The assembly conveyor line 11 is used for assembling the main unit, and the testing conveyor line 12 is used for testing the main unit. The main unit lifting conveyor structure 8, main unit lowering conveyor structure 9, and upper conveyor line 13 work together to transfer the main unit from the assembly conveyor line 11 to the testing conveyor line 12. The assembly conveyor line 11 and the testing conveyor line 12 are positioned at heights convenient for worker operation, while the upper conveyor line 13 is located above the workers.

[0027] Both the return conveyor line 1 and the upper conveyor line 13 include one horizontal arm and two vertical arms. The horizontal arm is arranged in a left-right direction and is located between the two vertical arms. The two vertical arms are located in front of and behind the horizontal arm, respectively, and are located at the left and right ends of the horizontal arm. A lifting structure can be installed at the junction of the horizontal arm and the vertical arms to realize the reversing conveying.

[0028] The assembly conveyor line 11, the inspection conveyor line 12, the product output line 3, and the longitudinal arm are all arranged in a front-to-back direction. The assembly conveyor line 11 and the inspection conveyor line 12 are arranged side by side. The main unit descending conveyor structure 9, the inspection conveyor line 12, the fixture descending conveyor structure 7, and the product output line 3 are arranged sequentially from front to back. One longitudinal arm (longer) of the upper conveyor line 13, one longitudinal arm (longer) of the assembly conveyor line 11, and one longitudinal arm (longer) of the return conveyor line 1 are arranged sequentially from top to bottom. The other longitudinal arm (shorter) of the upper conveyor line 13 is located directly above the front of the inspection conveyor line 12, and the other longitudinal arm (shorter) of the return conveyor line 1 is located directly below the rear of the inspection conveyor line 12.

[0029] The fixture lifting conveyor structure 6 is located between the front end of one longitudinal arm of the return conveyor line 1 (aligned with the lifting platform when in the low position) and the front end of the assembly conveyor line 11 (aligned with the lifting platform when in the high position).

An ionization air structure is located inside the assembly conveyor line 11, and a humidification structure is also provided at the assembly conveyor line 11. An inspection station is located next to the inspection conveyor line 12; specifically, the inspection station at the front of the inspection conveyor line 12 is a live inspection station, and the inspection station at the rear of the inspection conveyor line 12 is a non-live inspection station. A transfer station is located next to the fixture descending conveyor structure 7, used to transfer the main unit from the fixture 2 to a soft tray and then send them together to the product output line 3.

[0031] Among them, product output line 3 is a conveyor belt structure, with a packaging station next to it.

[0032] The fixture 2 is equipped with a socket 21 (fixed) and a soft pad 5 (placement). Specifically, the fixture 2 is a rectangular plate arranged along the front-to-back direction. Both its front and rear ends have soft buffer blocks 22 (specifically rubber blocks), and its upper side has a buffer layer (specifically a sponge pad). Both its left and right ends have soft limiting strips 23 (specifically sponge strips), and both its front and rear ends have notches 24 in the middle (specifically rectangular notches, angular notches, trapezoidal notches, arc-shaped notches, etc.). Its four corners are rounded. Both the soft buffer blocks 22 and the soft limiting strips 23 protrude upwards from the buffer layer. The soft buffer blocks 22 are arranged along the left-to-right direction, and the soft limiting strips 23 are arranged along the front-to-back direction. The socket 21 is located near the edge of the fixture 2. The chassis 4 and the soft pad 5 are placed side-by-side on the fixture 2, within the rectangular area enclosed by the soft buffer blocks 22 and the soft limiting strips 23. The motherboard is placed on the soft pad 5 to facilitate the installation of accessories.

The lifting and positioning structure is positioned directly opposite the notch 24. Specifically, the lifting and positioning structure is a pneumatic lifting structure, which is a conventional structure in the art, and detailed description is omitted in this embodiment.

[0034] Furthermore, in this embodiment of the invention, two power supply mechanisms 14 are arranged side-by-side on the rear of the assembly conveyor line 11 (corresponding to the start-up station), the front of the detection conveyor line 12 (corresponding to the live detection station), the upper conveyor line 13, the main unit rising conveyor structure 8 (specifically a lifting platform), and the main unit descending conveyor structure 9 (specifically a lifting platform) (this is not a limitation of this patent; three power supply mechanisms 14 may also be provided). The power supply mechanism 14 supplies power to the main unit. Correspondingly, two electrodes 25 (specifically smooth copper strips) are arranged side-by-side on the bottom of the fixture 2. The power supply mechanism 14 and the electrodes 25 are both arranged in the front-back direction. The two power supply mechanisms 14 are located directly below the two electrodes 25 and are in contact with the two electrodes 25 respectively. The two electrodes 25 are electrically connected to the socket 21, and the power supply mechanism 14 is slidably connected to the corresponding electrode 25. Specifically, the two power supply mechanisms 14 are located on the left and right sides of the lifting platform of the corresponding double-speed conveyor line or lifting return station, respectively. The power supply mechanisms 14 on the double-speed conveyor line and the lifting return station are correspondingly arranged to ensure that the main unit is continuously powered on.

[0035] In this embodiment of the invention, the power supply mechanism 14 includes a strip-shaped fixing base 41 arranged in a front-to-back direction and a plurality of conductive units 42 arranged side-by-side on it. The strip-shaped fixing base 41 is located on the lifting platform of the high-speed conveyor line or the lifting return station, and is insulated from the corresponding structure. The conductive units 42 are electrically connected to the power supply structure via wires and are hinged to the strip-shaped fixing base 41. The strip-shaped fixing base 41 has grooves along its front-to-back direction to accommodate the conductive units 42. Specifically, the strip-shaped fixing base 41 is a downwardly open channel steel, and the grooves are elongated holes. The conductive units 42 include a metal rotating arm and a metal wheel at its upper end. The lower end of the metal rotating arm is rotatably mounted on the strip-shaped fixing seat 41 via a left-right rotating shaft (made of metal and electrically connected to the corresponding wire). It is obliquely upward along the conveying direction of the fixture 2 (specifically, for the detection conveyor line 12, the metal rotating arm is obliquely upward from front to back, and a corresponding limiting structure is provided on the strip-shaped fixing seat 41). It can rotate downward, and a torsion spring is provided between it and the strip-shaped fixing seat 41 to allow the metal rotating arm to rotate upward. It can rotate downward into the groove. The metal wheel is arranged in the left-right direction and is specifically a copper wheel. Two strip-shaped grooves 26 are arranged side-by-side on the bottom of the fixture 2 (corresponding positions can be recessed to ensure the movement of the fixture 2). The strip-shaped grooves 26 are arranged in the front-back direction and open downward. Two electrodes 25 are located in the two strip-shaped grooves 26 respectively. The metal wheel is located in the corresponding strip-shaped groove 26, and its upper side contacts the corresponding electrode 25.

The two soft buffer blocks 22 are located on the left and right sides of the notch 24, and are rectangular rubber blocks. There are two sockets 21, which are located at the two ends of a diagonal of the jig 2 (notches are set at the corresponding locations of the buffer layer). The sockets are arranged along the front-back or left-right direction.
